Asking bid


In contract bridge, an Asking bid is a convention used to seek a slam accurately. There are two types - colour asking bids and notrump asking bids. Constructed by bridge pioneer Ely Culbertson in the 1940s, they have been superseded by other methods; however, one remaining commonly used asking bid is the 5NT Grand slam force.
The application of Asking bids requires making distinctions between the asking colour, the agreed trump and the two remaining side colours. Replies by partner are in accordance with a schedule of defined meanings.

What is an Asking bid ?

First there has to be an agreed trump colour. The trump agreement can be done explicit as well as implicit. Thereafter the first asking bid has to be either a double jump in a new colour not bid by the partner or the one who puts the asking bid forward, or at the fourth level. After an asking bid, the one who has put the first asking bid forward, will be like the Captain of a ship, and his partner has to reply to the questions. Only bids in the agreed trump can abort a series of asking bids.
Examples: After an opening of 1, partner's reply 3 establishes as trump. The bids 4, 4 and 4 are now asking bids. But also after a 1 opening, any double jump in a new colour is an asking bid, and agreed trump. After a 1 opening, 3, 4 and 4 are Asking bids. If 4 NT is bid before an asking bid has been put forward this will then be interpreted as Blackwood. But 4 NT is no longer a matter of the number of Aces, if 4NT follows after an asking bid.
The first asking bid is a question related to first and second controls. It is hence important to understand the definitions of the controls.
Defintition of first and second controls:
Also third controls can be of importance.
What's the significance of an Asking Bid ?
The first asking bid, equals the following question - "Do you have the first control in this colour ? Or if not, do you have the second control in this colour and one first control in other colour ?"
Another asking bid, has exactly the same significance.
Example:
West opens 1, and East holds this hand
Q J 9 7 3
-
A J 10 9
J 6 3 2
1 - 3
4 - 4
5 - 5
6 - pass
But if repeating the first asking colour, then the second asking bid equals the following question - "Do you have the second control in this colour ? Or if not, do you have an even better control in this colour and one second control in other colour ?"
Example with the same hand :
1 - 3
4 - 4
5 - 5
pass
Further Asking bids
If the reply to the first asking bid allows 4 NT to be bid, a 4NT-bid then is asking for the number of Trump-top controls, the Ace, King and Queens of the agreed trump. And partner replies 5 = I have none of these three cards, 5 = 1 such card, 5 = 2, 5 = all three. If the bidding has passed 4 NT, this bid can instead be bid as 5 NT.. But if this has been possible to bid already, at one level lower, then will 5 NT instead ask for Trump-excess, or the number of trump cards that so far has not been possible to show.
An asking bid in another colour can also follow. Then it's called "a second asking bid". Asking in the same colour twice is called "a repeated asking bid" however. And this is of a different significance compared to a new asking bid.

Example and replies

Example:
Auction:
1 - pass - 3- pass
4 ? - pass - Reply in table below
Hands with two voids are not taken in consideration. Presumably not by Culbertson, certainly not in the source.
The basic principles are -
  1. Without even the second control in the asking colour, reply negatively - logically trump at lowest level. This applies completely to the situation in the trump and side colors.
  2. Also with a second control in the asking colour, but no other first control, reply negatively - logically trump at lowest level.
  3. If the requirements of either a first control in the asking colour - or at least a second control in the asking colour combined with one or more first controls in Trump and the side colours are met, then reply constructively.
The constructive replies:
  1. With just one first control, this should be shown. Question colour raise, trump raise or a bid in the side colours.
  2. With more than one first control, the side colours comes first. Unless there totally are two Aces on the replier's hand.
  3. 4 NT always means exactly two Aces
  4. 5 NT always means at least three Aces
Tactics
When a slam seems possible, and especially when this depends on partner's controls in a certain colour, then asking bids may well be the road to follow. If asking in a colour in which you have either the Ace or the King, you may get splendid excess information.

Applicability

Asking bids, although developed for the Culbertson bidding system, which today largely has become obsolete, can be used in combination with most natural bidding system, such as Acol, Five Card Major and others. Like Blackwood and Cue bids, Asking bids are Slam-seeking.
It is indeed possible to use Asking bids together with Blackwood, even in one and the same deal. But Asking bids can never be used in combination with Cue bids, as they can't be distinguished from each other.
The advantages of Asking bids increase especially if used together with Culbertson's 4 and 5 NT conventions. Here the rules are very clear:
"If a series of questions begin with 4 NT, then that specific bid is Blackwood. But if the first question has been a bid in a new colour, then the 4 NT instead asks for the partner's trump top quality." The 4 NT bid is then asking for the number of top three trumps, then a later 5 NT bid, asks for additional trump length. Whilst a 5 NT bid not preceded by any 4 NT bid, equals the Grand slam force convention.
After a first Asking bid, then the 4 NT bid asks for "trump top quality".. If 4 NT is followed by 5 NT, then that bid asks for "trump length". Here the replies are based on what's the minimum number of cards for a usual trump agreement length., but is often the case. Cue bids are from that perspective different.
And it has to be added that Cue bids today more or less has put the Asking bids to history. But Culbertson's 5 NT Grand slam force is still in use.

Full auction example

Here West has 13 HCP and East only 5 HCP, a total of just 18. If adding distribution points to both hands, West and East would according to most such calculations still be a little short of the required points for a game even ! But not everything can be measured in numbers - and a Grand slam in really is the correct contract below - and must be considered to be safe regardless of the remaining distribution and the opponents' lead.
Both North and South are silent during the auction. Provided West begins to speak in the auction, only a wrench distribution in North's favor would disturb this bidding. A doubling of the opening bid could be disregarded from by East. It is however a constructed example, made in order to show the benefits of Asking bids in combination with Culbertson's 4-5 NT combination.

After West's opening, East confirms as trump. As West has A, the 4 Asking bid is looking for second control and any possible first control. East now can show his void in, as he has the second control in. Now West wishes to know whether East has any of the three top trump cards, which may seem a bit awkward given all three top trumps are on West's hand, but this bid later enables the 5 NT-bid to be a trump length issue. Hence East's reply 5 is no surprise to West, who now with 5 wonder if East also has the third control in. And the King - Queen is indeed both a second and a third control - and as East's void in is "covered" with five trumps, East can now declare also his third control in. Now West finally wishes to be certain of a really good trump support - 5 NT. And East's 6 shows two more trump cards than his/her 3 reply to West's opening earlier has shown. And it's now easy for West to determine the final bid, a 7 Grand slam contract.
The example is a splendid illustration the significance of distribution combined with the difficulty to find Grand slams especially, even when they are easy to see - on 26 cards. As well of how Asking bids combined with not just trump top, but trump length, can be of great help.

History

The Asking bids were invented by one this card game's true pioneers, Ely Culbertson, but was later removed from Culbertson's system in favor of Cue bids and other slam seeking conventions. But they can co-exist with some other slam seeking conventions, such as most variants of Blackwood, in the sense that both can exist - but only one of them at a time. Culbertson's Asking Bids can be combined with other bidding system, like Acol and Five-card majors, although originally designed for Culbertson's own one.
